Map “A act/byp” and “B act/byp” to the same aux switch. This way you can bypass both Presets at the same time with one switch.
What’s happening is the H90 is providing a direct connection to the outputs for I/O 1&2 when it’s bypassed. The inserts, however, remain open since I/O 3&4 were designed as effect loops. They remain open in case loop effects are still trailing out when the Program is bypassed. 3&4 are connected to the algorithms internally.
